Application filed August 19, 1910. Serial in 577,911.

Massachusetts, have invented an Improveinent in Means for FacilitatingWarp 'gnchange in Looms; of which the 'followlng description, inconnection with the accompanying drawing, is a specification, likecharacters on the drawingrepresenting like parts.

This invention has for its object the production of meansforfac'ilitating a change of the warp in a loom, whereby'the warp andits stop-motion detectors can be removed intact, either when anew warp1S to be substituted or if the warp is to be laid aside temporarily. a La My present invention is more particularly designed for use inwarpstop-motion mechanism wherein the detectors are thin, flat metallicstrips havin closed slots for the reception of the gui e or supportingbars.

, I-have shown my invention in connection with a warp stop-motion of thetype wherein the detectors are mounted independently of the sheddingmechanism, as in United StateaPatent-No'. 699,117 granted April 29, 1902to Stimpson. I

The various novel features of my invention will be fully described inthe subjoined specification and particularly pointed out in thefollowing claims. r

Figure 1 is a transverse section of a portion of a loom with a warp stopmotion applied thereto of the type referred to, and above the detectorsI'have shown a part of the removable meansfor retaining the detectorsand their supports in position on the ,threadswhen the'warp is-removed,.to illustrate, the manner in'which my invention is used; Fig. 2isafront elevation of the stopmotion mechanism, centrally broken out,

' i and showing the removable retaining means applied, in readiness forthe removal of the detectors; Fig. 3 is an enlarged view in elevation ofone of the retaining members.

- In Fig. 1 the layflA, reed A, harnesses C, and whip-roll D are all ofusual construction, eachside of the loom being provided with a stand A.supporting-a bracket B which carries the rock-shaft F having theattached feeler f, the back-stop bars "13 B, and warp rest M beingmounted on the brackets B as in the Stimpson'patent referred to. Thedetector-supports (1", extended through longitudinal slots (1' .in thethin flat metal detector dhaving warp-eyes (Z are as in said patent,each support d" having a notch 8, Fig. 2, to fit over the shank of atransverse, headed bolt 10, passed through the lug b of each bracket B,a nut 12 on each bolt clamping the supports secur ely in place .undernormal conditions. Each bank or series of detectors 0? is strung on oneof the supports (15*, and in mypresent invention I have providedmeansfor engaging the two supports near their outer ends, be-

yond the detectors, and locking such sup-v ports together so that theyand their detectors can be removed bodily from the loom when the nuts 12are loosened. Each of the two retaining members is made as a flat metalplate 20, bifurcated'to presen two separated depending legs 21, eachhaving a longitudinal slot 22 open at its lower end, said slots being inparallelism and spaced apart equal to the distance between the twodetector-s'upports d". A latch 23 is pivoted on each leg at 24, aboveand at the inner side of the slot 22, the upper end of the'latch beingpreferably out-turncd, at 25, and the inher edge of thelatchis notchedto form a substantially rectangular seat 26, slightly longerthan-thedepth of a detector-support. Each of the plates is apertured to receivea connecting rod 27, provided with suitable means, as cotter pins-28, tolimit the out-ward ward each other, until each support enters the seat26v of the adjacent latch (see the are thus removable bodily,

latch at the right Fig. 3). The supports d" are now locked in theslotted legs 21 of the plates 20, said plates being outside the banks ofdetectors, as shown in Fig. 2, and by loosening the nuts 12 saiddetector-supports can be lifted out, the connectingrod 27 serving as ahandle for the purpose. If desired the plates20 can be directly liftedby the weaver by means of the finger-holes 29 in the plates. Thedetectors and their supports with the reed and harnesses, whether thewarp is to be taken off the loom temporarily or whether a new warp is tobe tied in, and in the latter case the old warp will be cut in front ofthe reed and back of the stop-motion. Inasmuch as the properrelationship or spacing between the detector-supports is maintained bythe means described it will be apparent that in-restoring such parts tothe loom the supports are positioned to be directly applied to the bolts10, aigreat deal of time being thereby saved. Preferably the latches arepivoted to the end plate 20 tightly enough to be held frictionally inoperative or inoperative position until removed therefrom by the weaverin the use of the device.

The end members or plates 20 are bifurcated as described to enable thelegs 21 to clear the Warp-rest M when the device is used, and as theseats- 26 are offset from the pivots 24: the weight of the supports (6*and the detectors tends tomaintain the latches closed or operative whenthe parts are moved from place to place.

When the detectors and their supports are restored to a loom thesupports d are first clamped in place and then the latches are swungoutward to release the supports, whereupon the retaining means is liftedup and out of the way, the legs 21 being thereby drawn off from thedetector-supports.

Various changes and modifications in details of construction andarrangement may be made by those skilled in the art without departingfrom the spirit and scope of my invention as set forth in the claimsannexed hereto.

Having fully described my invention, what I claim as new and desire tosecure by Let'- ters Patent is 1. In a warp stop-motion for looms,having series of longitudinally slotted detectors to cooperate with thewarp threads, a transverse support extended through the slots of eachseries of detectors and adapted to be removably mounted in the loom, andmeans to cooperate temporarily with said supports and enable them withtheir detectors to be removed bodily from the loom, said meanscomprising connected members to co operate with the supports outside theseries of detectors thereon, and devices to lock the supports to saidconnected members.

2. In a warp stop-motion for looms, having series of longitudinallyslotted detectors to cooperate with the warp threads, a transversesupport extended through the slots of each series of detectors andadapted to be removably mounted in theloom, and means to cooperatetemporarily with said supports and enable them with their detectors tobe removed bodily 'irom the loom, said means comprising connected endmembers having open slots to receive the detector-supports near theirends, and devices carried by said members to cooperate with and retainthe supports in the slots of the end members, whereby the supports aremaintained in normal position relatively to each other when removed fromthe loom.

8. In a warp stop-motion for looms, a plurality of paralleldetector-supports adapted to be removably mounted in the loom, seriesofdetectors to cooperate with the warp threads and each longitudinallyslotted for the reception of a support, and temporarily attachable meansto effect bodily removal of the supports and their detectors, said meanscomprising parallel end plates and a connecting rod, each plate havingslots open at their lower ends to receive the detector-supports, andlatches pivotally mounted on the plates and provided'with seats toreceive the supports and retain them in the slots .of the plates whenthe latter are lifted to withdraw the detector-supports from the loom.

4. Means for facilitating warp change in looms, comprising parallel endmembers having depending legs provided with parallellongitudinal slotsopen at their lower ends, to receive transverse detector-supports removably mounted in the loom, a latch pivotally mounted on each end memberadjacent a slot and having an open seat on its inner side, to receivethe detector-support and retain it in the slotted leg, whereby the saidsupports can-be removed bodily -from the loom and maintained properlyspaced apart when removed, and a permanent connection between said endmembers, outward movement of the latches on their pivots releasing thedetector supports to permit withdrawal of the slot ted end. members.

5. In a warp stop-motion for looms, a plurality of paralleldetector-supports adapted to be rcmovably mounted in the loom, series ofdetectors to cooperate with the warp threads and each longitudinallyslotted for the reception of a support, and temporarily attachable meansto effect bodily removal of the supports and their detectors, said meanscomprising connected parallel end plates bifurcated to present separateddepending legs, each leg having a longitudinal slot therein open at itslower end, to receive a detectorsupport, a locking latch pivoted on eachleg adjacent the slot and adapted when operatively positioned to closethe slot below the In testimony whereof, I have signed my detectorsupport and thereby retain said s'upname to this specification, in thepresence of port in the leg, and a finger-piece on each two subscribingwitnesses. latch, the end plates engagin the detector- WILLIAM MCCASLIN.
